To all whom it may concern:

Be it known that we, ARTHUR EDWARD STROUD'and HAROLD FREDERICK SOAR, subjects of the King of. Great Britain, and residents of Long Eaton and Alvaston, respectively, both in the county of Derby, England, have invented new anduseful Improvements in Looms, of which the following is a specification. I

This invention relates to improveinents in narrow-ware looms in which a number of tapes,'ribbons, and similar fabrics are si-..

also improvements in the means for taking up the work, and improvements in the general arrangement and construction of the loom.

In the drawings :-Figure 1 is an end elevation of a vertical loom constructed according to this invention. Fig. 2 is a transverse section of the same. Fig. 3 is a part transverse section of the loom to an enlarged scale showing the reed in the beat up position. Fig. 4- is a part sectional front elevation of Fig. 3. Fig. 5 is a front eleva-.

tion of the shuttle. Fig. 6 is an elevation of awork take-up roller, and Fig. 7 illus trates a modified form of shuttle and shuttle guides.

The loom shown in the drawings is provided with a central frame which includes the front angle rail 1 and the back angle rail 2. The ends of these rails are connected by brackets 3, Fig. 1, at both ends of the loom to vertical rods 4 which are fitted to slide in fixed guides 5 and are rigidly connected together by cross bars 6 and 7. 7 Between the cross bar 7 and the lower guides I 5 there are springs 8 by which'the weight of the central frame and its connected parts is wholly or partially balanced. The central frame is driven at both ends to reciprocate vertically by crank pins 9 on the driving shaft 10, such cranks being coupled to the cross bars 7 by links 11, levers 12 and 13, andlinks 14, the parts being so arranged that when the levers 13 are approximately vertical the central frame is at, or near, its lowest position and practically rests in this position for a shortperiod of time.

Mounted upon the rails 1 and2 there are brackets '15 which are grooved at the sides to form guides for the shuttle 16, and in carried in bearings which are attached to the rails, and each shaft is provided with" toothed pinions 18 by which the shuttles are traversed to and fro through the sheds. The shafts 17 at both ends of the loom, are fitted with driving pinions 19 and are oscillated by quadrants 20 which are mountedupon axles carried. by the cross bars 6. Each quadrant is provided with adriving stud21, which is adjustably attached to the connection with each rail there is a shaft 17 quadrant, and engages with a slot in the end of a lever 22 which is pivotally mounted upon an axle 23' carried by-the standard 24.

The lever 22 is driven from the shaft 10 through the circular gear wheels 25 and 26, and the elliptical or cam shaped gear wheels 27 and 28 which are carried on fixed axles 29. The wheel 28 gives motion to a crank pin 30 upon a disk, crank or wheel 60 which is connected to the lever 22 by a link 31, this gearing being so designed and arranged that the shuttles make a back to front, or front. to back traverse for each up and down movement of the central frame and so that the shuttles work in unison with the movement of the central frame. I

In the modification shown in Fig. 7 the shuttle guides are circular arcs struck from a convenient center and the shape of the shuttle is modified accordingly. The shut-' tles are traversed by pinions 18 on the shafts 17 by the means and in the manner substantially as herein before described with reference to the straight shuttle guides-shown in Fi 3.

The shuttle l6, 5, for use in the improved loom is preferably in the form of an approximately triangular frame the base of which is provided with gear teeth 32 which engage with the teeth of the shuttle driving pinions 18. The shuttle thread a is 'wound upon a thin spool or bobbin 32 which is fitted to rotate on a fixed axle 33 which is at right angles to the length of the shuttle and is carried by the cross bar 33, the shuttle being held upon the axle by a spring from the shuttle.

The threads I) for each piece of tape are wound upon separate bobbins 38 and each bobbin is provided with an adjustable brake or tensioning lever 39. The threads pass over guide rods 40 to the tensioning rods 41 and upward to a fixed Wire net thread guide 42. From this guide the threads pass upward to thin steel bars 43 which are suitably perforated for the threads and each "bar carries one thread for each piece of tape to be made. The bars 43 extend the full width of the machine and for plaintapes the bars are divided into odd and even numbered sets and are. or may be, actuated to form the shed by any suitable arrangement of cam mechanism, but for the manufacture of fancy or patterned goods, the bars 43 are actuated to select the threads by a jacquard or other similar pattern mechanism.

The reed 44 is attached to the-inner ends of the shuttle guide brackets 15 and the work 0, as it is made is taken up by rollers 45 the surfaces of which are suitably roughened. These rollers'are positively driven by I a worm 46 and worm wheels 47 on the ends of the axles carrying the rollers, and preferably also one or both of the rollers are connected totheir axles by a ratchet or other clutch 48, Fig. 6, so that any piece of work can be drawn backward when required. The

' woven tapes pass over a roller 49, which may if desired be rotated and around guide rods 59 and 51, and atthe rod 51 the tapes are divided. the odd, or even numbered, tapes being wound up on the front bobbins or creels 53, and the even, or odd numbered tapes, being wound up. by the back bobbins or creels 53 and both sets of bobbins or creels are frictionally driven by cords 54 from pulleys or rollers 55..

In a modification of the--.work take-upv mechanism particularly suitable for narrow widths the rollers 45 are loosely mounted on their axles and the roller 49 is positively driven for taking up the work. When the rollers 45 are positively driven, as shown in the drawings, the roller-49 and the rod 59 may be dispensed with and the tapes be passed from-the rollers'45 direct to the rod 51 where they are divided.

The drawings illustrate the construction. of a loom in which the reed 44, the shuttles 16, and the shuttle guiding and actuating mechanisms are carried by a vertically moving central frame and also arrangements of mechanisms. for actuating the central frame and the shuttles. These parts are so timed. relatively to each other that when the reed is in its lowest position the shuttles are in the central position half way through the shed, and soon after the shuttles bave passed this position the reed commences to rise to its beat up position. After the completion of the beat up motion the reed commences its downward movement and during such movement the sheds are changed and the shuttles commence their return. traverse and reach their central position at approximately the same time as the reed completes its down ward stroke.

We claim 1. In a narrow ware loom the combination of a central frame, the shuttles and shuttle driving mechanisms carried by such frame,

' lowest position substantially as herein described.

2. Ina narrow ware loom the combination of a stationary supporting frame, a movable frame supported in the stationary frame,

the shuttles, gear teeth on the shuttlesf toothed pinions. for driving the shuttles, shafts carrying such toothed pinions supported in the movable frame, a toothed quadrant for actuating the shafts pivotally united with the movable. frame, a slotted lever for driving the quadrant pivotally supported in the statlonary frame, and crank and elliptical toothed gear wheels'for operating the slotted lever substantially as herein described.
